Details:

I have read the documentation and it states nothing about not
using computed variablenames as dependency, so I tried it.

I wanted to have a variable containing destinationfiles and
for each destinationfile a list of auxiliary files (i.e.
included TeX files).

In reality it makes no difference if the file, in my example
the content of variable all_TEX is present or not. "blub" is
not present and the echo comes with the expected output, with
a present file the same thing happens.

I do not know if this is intentional, a bug, or simply been
forgotten to write down in the documentation.

I shortened it for a quick insight:
#----------CUT HERE---------#
all_TEX=blub

all.dvi: $($(patsubst %.dvi,%,$@))
        echo "Text: " $($(patsubst %.dvi,%, $@)_TEX)
#----------END CUT----------#
